The science on viral transmission through feed and feedstuffs is relatively young, but research in the past year has yielded some interesting and useful information. New research improves upon current understanding of how the deadly African swine fever (ASF) virus survives in feed. Research shows it lasts much longer than scientists originally thought.
Earlier studies evaluated the half-life of Senecavirus A (SVA). The half-life is the amount of time that it takes for half of a virus that may be contaminating feed or a feed ingredient to die off naturally.
“We wanted to get information as quickly as we could and make it as best as possible so we chose Senecavirus A because it’s not a regulatory virus and you don’t need a high biosecurity lab to do the work,” explains Paul Sundberg, DVM, executive director of the Swine Health Information Center (SHIC).
